Hand-stamp



UNITED STATES PATENTOEEIGE.

GEORGE E. WOODBURY, OF CAMBRIDGE, MASSACHUSETTS.

HAN D-STAMP.

Speciication forming part of Letters Patent No. 59,497, dated November 6, 1866.

To all whom it may concern:

Be it known that I, GEORGE E. WOODBURY, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement on a Canceling or Hand Stamp, and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, of which- Figure l is a front elevation of the machine or cancelingstamp 5 Fig. 2, a vertical section of the same; Fig. 3, a side elevation of the same 5 Fig. 4, the bottom of the chase and cylinder-chamber.

The letter A represents the frame of the ma chine 5 B, the plunger; C, the printing-cylinder chamber 5 D E F, printing-cylinders; a b c, their thumb-nuts; d ej', their shafts; g, print ing-ribbon; h, chase; i i, spring-catches; k, locking-catches.

N ow that others may better understand my invention and be enabled to make and use the same, I will proceed to explain.

. Theuse of the canceling-stamp is wellknown.

Figs. l, 3, and 4 in the accompanyingdrawings give different views of the machine ready for use; andFig. 2 is a section of the same, also ready for use.

I make my machine of metal or of any suit able material. The frame, consisting of the bottom part and the handle, the upper part of which supports and keeps in place the plunger, I make of cast-iron or other cheap and suitable material, and it may be made in one or more pieces, as seen in Fig. 2.

The plunger B, I also make of brass or other suitable material, and it may be a solid or holloW cylinder.

The printing-cylinder C is made of cast-iron, or may be of any suitable material, the outside form of which is seen in Fig. l. By examining Fig. 2 the inner arrangement of this cylinder is clearly seen.

In canceling I wish to arrange the month, day, and year in order, as seen in Fig'. 4. For the month I putin the cylinder l), and to turn it for different months I put through the shaft el, on the end of which is a thumb-nut, a.. This cylinder is kept in place by a pin going through the outer cylinder-case, C, or by a spring and lock-catch, z', as seen in Fig. 2. On the wheel or cylinder is set in type each month in the year; or it may be marked on a strip of metal going round the wheel.

For the day I have placed the wheel or cylinder E as seen in same figure. Its shaft and thumb-nut e and Z1 are moved independently of the others. The wheel has set in type or marked on it the number of days in a month, similar to the latter described, and is turned by the nut b, and the shaft e is made iirm to the cylinder E. The number' for the day is kept in place by spring-catch K.

To change days, lift up the catch and turn the nut; the catch will spring itself into its place in order.

To set the cylinder for years, turn in a similar manner the shaft and wheel F by the nut C. The type, ofcourse, can be changed readily by picking out one and setting in another but the year being set and the month set, there is but little trouble in turning the Wheel or cylinder for each day.

The chase is made in the usual form, on which is engraved the name or letters desired.

- The printing-ribbon gis kept in place by the two cylinders, as seen in Figs. 4 and l, and their cylinders are made firm to the printing chamber. The ribbon may be easily taken out by drawing the pin thatkeeps the small cylinder iu its place and a new one put in its place. The manner in which this operates may be clearly seen by referring to Fig. 4 in the drawings.

In those two cylinders for holding in place the printing-ribbon will be seen small spiral springs. Those springs keeps the shafts winding the ribbon in order. On pulling out the shafts the caps or ends of the cylinders also come oft', and the whole is easy to put in order again. Around the plunger, also, is a spiral spring, so that when it is plunged down it will immediately spring back into its former position. The plunger is fastened to the printing-cylinder chamber by a socket in the plunger, into which the plug of the cylinder-chamber is crowded, or itv may be by a screw or other convenient fastening.

In the ordinary mode of fastening the type in the stamps for months, days, and years by an endless chain passing up the cylinder of the plunger, or by fastening the type in, when out of order than any caneelingstamp now in use.

I elaimo l. Thecombination and arrangement of the three type-cylinders D E F, with the shaft of the center one extending entirely through the plunger, and the shafts of the other two extending through opposite sides of the plunger, and each shaft provided with a hand-wheel to turn and set it, substantially as described.

2.V In combination with the above-claimed devices, the movable ink-ribbon, substantially as described.

GEORGE E. WOODBURY.
